Bryan Johnson Hair Loss Protocol

Johnson uses a custom topical formulation that he applies each evening before bed.
This formulation contains evidence-based ingredients for treating male pattern baldness and promoting hair growth.
Bryan Johnson’s Custom Topical Hair Formula Ingredients
Johnson uses a custom blend of the following ingredients in his evening topical treatment:
Minoxidil 5%
This vasodilator medication is clinically proven to help regrow hair in some cases of male pattern baldness.
Minoxidil likely works by increasing blood flow and nutrients to hair follicles.
There are tons of products on the market. They all have the same compound, so there’s no need to overspend here.
Finasteride 0.25%
Applied topically at this dose, finasteride helps reduce DHT levels in the scalp, a hormone linked to male pattern hair loss.
This one generally requires a prescription.
Caffeine 1%
Caffeine may support hair growth by blocking the effects of DHT when applied to the scalp.
Azelaic Acid 1.5%
This ingredient has anti-inflammatory, anti-androgenic, and antioxidant effects. It may help with dandruff and hair loss.
Diclofenac 0.5%
This NSAID medication may stimulate hair growth and prevent hair follicle miniaturization when applied topically.
Tea Tree Oil 5%
Tea tree oil has antimicrobial effects that can help combat inflammation and dandruff.
Rosemary Oil 0.37%
Rosemary oil may increase circulation in the scalp to encourage hair growth.
Ginkgo Biloba 0.05%
Ginkgo biloba is an antioxidant that may boost hair growth by improving microcirculation.
Biotin 0.01%
Biotin supports keratin infrastructure of hair and nails. It may strengthen hair.
Hair products with Biotin often contain other compounds, such as Minoxidol.
Melatonin 0.0033%
This hormone supplement may have hair growth benefits related to its antioxidant effects.
By using a combination approach, Johnson aims to maximize topical treatment benefits. However, individual results will vary.
While this exact formula isn’t available for purchase, it’s possible to pick and choose from this list to build your own solution.

Bryan Johnson Red Light Laser Cap Routine
Johnson uses a red light laser cap for 6 minutes each morning.

Red light laser caps may help improve hair growth by enhancing cellular energy production in the follicles.
On this site, he mentions using a Capillus.

However, the pro version of this product is currently listed at around $3,000.
We did a deep dive into red light therapy devices and found some more accessible-priced alternatives below.

Bryan Johnson PRP and Dutasteride Injections
Once a month or every three months, Johnson gets platelet-rich plasma (PRP) injections.
PRP contains a high concentration of growth factors from his own blood.
Research indicates PRP injections may stimulate hair growth in some cases of androgenetic alopecia.
Johnson also takes dutasteride.
This blocks DHT similarly to finasteride. The addition of dutasteride likely enhances the hair growth effects of PRP therapy.
He may also receive standalone dutasteride mesotherapy injections between PRP treatments.
Bryan Johnson Supplements for Hair Health
He also takes oral supplements containing ingredients that may support hair growth and quality.
Collagen
Some research indicates that collagen supplements may support hair thickness and growth.
Collagen contains amino acids like glycine and proline that makeup keratin, a structural protein for hair.
One study found that collagen peptides increased hair growth and density in women with age-related thinning.
Vitamin D
Vitamin D plays several roles in regulating the hair growth cycle and follicle function.
Vitamin D deficiency has been linked to hair loss conditions like alopecia areata.
- Associated with reduced risk of cognitive decline
- Enhance brain blood flow and neurotransmission
- Potential mood elevation if deficient
Vitamin D from the diet or supplements may help maintain healthy hair follicles and prevent shedding.
Antioxidants
Antioxidants help counter oxidative stress, which can damage hair follicles and cause deterioration.
Taking supplements with antioxidant compounds like vitamin E, vitamin C, and selenium may support hair health.
- Protects brain cells from oxidative stress and damage
- Synthesizes neurotransmitters like norepinephrine
- May aid in improving mental clarity
However, more research is needed on their efficacy for treating hair loss.
While oral supplements may provide general hair health benefits, they aren’t proven treatments for genetic hair loss conditions.
Bryan Johnson Philosophy on Hair Loss Prevention
Bryan Johnson believes in taking preventative measures rather than waiting for hair loss to progress further.
By using a combination of proven and experimental treatments, he aims to maintain the hair he still has and potentially regrow lost hair.
While his intensive protocol is time-consuming, Johnson has built the treatments into his daily and monthly routines as habits.
This makes maintenance more sustainable in the long term.
However, he acknowledges his regimen may seem overwhelming to start.
